We affirm that the Bible, containing the Old and New Testaments, is alone the only infallible, inspired Word of God, and that its authority is ultimate, final, and eternal. It cannot be added to, subtracted from, or superseded in any regard. The Bible is the source of all doctrine, instruction, correction, and reproof. It contains all that is needed for guidance in godliness and practical Christian conduct.
It is the testimony of both the Old and New Testaments and of the Christian Church that God is both One and Triune. The biblical revelation testifies that there is only one God and that He is eternally existent in three persons—Father, Son, and Holy Spirit.
